Chuck Liddell and the 15 Strangest Personalities in UFC History

The UFC always entertains diverse fighters with vast personalities.

From math teachers turned middleweight champions to backyard street fighters turned professional KO artists, as well as ex-WWE champions, mixed martial arts' biggest franchise has boasted a variety of fighters who've made their mark outside of the Octagon just as they did inside.

Some are more eccentric than others, but regardless of age, ethnicity, MMA background and performance inside the cage, they all have one thing in common:

They just made the list for the top 15 strangest personalities in UFC history.

Joe Rogan not included.

15. Kimbo Slice

Easily one of the most popular figures in Internet fight video history, Kimbo Slice quickly transformed from a YouTube sensation into a contracted UFC fighter.

His tenure inside the Octagon wasn't for long, but the guy has personality to match his scraggly beard, spiderweb tattoos and hardcore street persona.

As many people witnessed during his days as a competitor on Spike TV's The Ultimate Fighter, Slice is a fairly deep individual.

He's a quick learner and great teammate who fights for his family, and he ultimately shed any stereotypes about his street antics.

For that, he comes in at No. 15.

14. Rich "Ace" Franklin

For the most part, Rich Franklin isn't all that strange or crazy, but he has shouldered a rather odd path to becoming a professional UFC fighter.

Before Franklin dove into MMA, he was a math teacher at a high school in Ohio.

Any guy that would rather get his face smashed in than grade algebra homework is a strange dude in my book.

On a side note, when are Dana White and Joe Silva going to give Franklin the No. 1 contender fight he deserves?

13. Diego Sanchez

Plain and simple, Diego "The Dream" Sanchez is a weird guy.

Whether it's his pre-fight stare-downs, post-fight celebrations or mid-fight intensity, Sanchez has a lot of anger.

With that said, he arguably has a few screws loose upstairs and definitely isn't afraid to show it.

No matter the circumstances or who he's fighting, Sanchez always seems to bring his personality into the Octagon.

12. Josh "Kos" Koscheck

Josh Koscheck is one of the most recognizable fighters in the UFC today.

His curly yellow hair and strong wrestler's mentality are only the beginning.

Koscheck is one of the sport's most eccentric trash talkers, ranging from pulling pranks on Georges St. Pierre during his time as a coach on The Ultimate Fighter to beating up an employer in a rock n' roll music video.

With that said, it's difficult to discredit "Kos" as one of the most unpredictable showmen in the UFC.

11. Nick and Nate Diaz

Originating in Stockton, Calif., Nick and Nate Diaz bring their rough street-fighting days into every bout they have.

Nick actually competes in triathlons as part of his fight training, which a lot of people don't know.

Brother Nate, who is arguably one of the best game-time fighters in the welterweight division, is known for his antics inside the ring.

Both Diaz brothers love to brawl. They seem to feed on the pain of their opponents as well as themselves.

If personality was an advantage in a fight, each guy would be the champion in his respective division.

I guess it's due in part to their hard-nosed Cali egos, but it's obviously a combination of skill and downright wackiness.

10. Chuck "The Iceman" Liddell

Liddell may be the most infamous fighter in MMA history, helping put the sport and the UFC on the map in the United States.

He may be known for his dangerous hands and intimidating Mohawk, but Liddell's craziness outside of the Octagon makes him a perfect candidate at No. 10.

Not for nothing, but the guy used to fight drunken college students at a bar.

He's been in numerous movies, owns a few bars and has the coolest MMA shorts ever.

Too bad he's retired because "The Iceman" was one to remember.

9. Brock Lesnar

Brock Lesnar is an animal.

No, he's literally an animal.

Lesnar lives in the middle of nowhere in Minnesota, somewhere between a tree and a rock. His seclusion is somewhat understandable, but the guy literally only watches TV for hunting shows.

He's married to former WWE wrestler Sable, grows some really awesome beards, rocks a very unusual Viking-like sword tattoo and takes crap from nobody.

If reincarnation is true, there's no doubt in my mind that Lesnar was Paul Bunyan in his previous life.

Despite his odd lifestyle, Lesnar does back it up inside the cage. He's racked up some great victories in the UFC and has brought an edge that's similar to his past antics as WWE champion.

8. Chael Sonnen

Any guy who calls out Anderson Silva in the fashion that Chael Sonnen did deserves to be in the top 10 strangest personalities ever.

Sonnen's actions over the past few months, which include a huge victory over Brian Stann and a promise to retire from the UFC if Silva beats him in their next fight, have created a buzz around one of the best middleweight fighters in the world.

If you have any free time, check out some of Sonnen's interviews. The guy is seriously entertaining, like a UFC version of Floyd Mayweather Jr.

7. Chris "The Crippler" Leben

Chris Leben is nuts.

He's tattooed nearly everywhere, paints his fingernails and resides in Hawaii, where he climbs mountains to clear his head.

While Leben's chin serves as his most admirable fighting attribute, his toughness outside of the Octagon has helped him survive a nasty car crash and a nine-month steroid suspension in 2008.

At this point, Leben's toughness and willingness to take the most punishment of anybody directly translate into one strange persona.

6. Tito Ortiz

Regardless of his recent decline in the UFC, Tito Ortiz's heralded past will always make him one of the most personable fighters in MMA  history.

The "Huntington Beach Bad Boy" is one of the sport's most talented competitors, as well as a trash-talking expert.

Ortiz is a give-it-all fighter, and that's exactly what makes his personality reign supreme. 

His past media battles with UFC President Dana White only add to his madness, making him relatable to anybody who's ever hated his boss.

He's a legend inside the ring and outside of the UFC and controls one of the strangest personalities of all time.

5. Ken Shamrock

Ken Shamrock is in fact "The World's Most Dangerous Man" inside the Octagon, but he's had a tailored past of personality quirks as well.

His feuds with Tito Ortiz and Dan Severn have been heavily followed and are some of the best fighter duels in UFC history.

Shamrock's stint in the WWE wasn't a complete failure, but it took away from his potential in the UFC during the mid '90s.

Regardless, Shamrock is one of the most intense people to grace the sport, matching it with great ability and pre-fight publicity.

4. Quinton "Rampage" Jackson

This one was easy.

"Rampage" Jackson is a head case. The good kind.

Jackson is one of the sport's most infamous fighters, gaining glory in Pride and the UFC.

His recognizable howling is one of the more famous acts around, and his role as B.A. Baracus (originally portrayed by Mr. T) in The A-Team remake has made him a bona fide movie star.

As many of the guys on this list, Rampage has top-tier trash-talking ability.

He's eccentric, wild, downright hilarious and knows how to get under people's skin.

Because, in the end, he is a "street general."

3. Jason "Mayhem" Miller

If this picture doesn't do Jason "Mayhem" Miller justice, then I don't know what does.

In my opinion, Miller is No. 1 on this list, but I couldn't work up the courage to put him there because he hasn't been in the UFC in a while.

"Mayhem" is the current host of MTV's Bully Beatdown, a coach on Spike TV's The Ultimate Fighter and dyes his hair literally every week.

Miller is extremely personable, making jokes and creating weird outlooks on life at every turn.

Let's be honest: Any guy who enters the ring wearing a hockey mask has some serious personality issues.

I love it.

2. Clay Guida

First off, if you didn't know, Clay Guida lives in an RV.

He prefers it.

With that said, the guy is crazy.

Masking his persona with long hair, tattooed arms and a classy outlook on his competition, "The Carpenter" is one strange dude.

But one who is arguably the most likable fighter in UFC history.

He's a man's man.

Guida may live on the side of a highway and wash his clothes in a river, but he'll go down in MMA history as one of the most expressive individuals ever.

1. Forrest Griffin

Numero uno, Mr. Forrest Griffin.

Besides looking like a chimpanzee, Griffin possesses a few other strange tendencies.

The New York Times bestselling author consistently proves that fighting crazy is sometimes more effective than fighting with skill.

Not to say Griffin isn't well trained in MMA, but his fighting style is similar to his persona.

He doesn't seem to be bothered by losing a fight if it's entertaining for the fans.
